Patent CA-2348320-A1 (CA)
Inventor: LAVILLE FREDERIC
IPC: G01M7/00
Filed: 2001-05-18
Abstract: A modal analysis method and apparatus for acoustically determining dynam ic vibration characteristics of a structure, including natural frequencies, mod e shapes and damping factors, is based on a Multiple-Input-Single-Output (MISO ) model. The method and apparatus involve generation of an acoustic excitation signal toward n spatially distributed locations associated with the structur e while the latter is held to allow vibration thereof, one of the locations being chosen as a reference location. A series of microphones are disposed at the locations to produce m complementary sets of n input acoustic pressure-related electrical signals, one of these being chosen as a reference signal associated with the reference location. A Fourier analysis is performed on the sets of input acoustic pressure-related electrical signals to provide corresponding sets of correlated input acoustic pressure-related data in the frequency domain including reference data associated with the reference signal. A vibration transducer such as an accelerometer is used to sense induced output vibration in response to the acoustic excitation at a reference point on the excited structure corresponding to the reference location to produce m complementary sets of output vibration response electrical signals, which are then converted through Fourier analys is into corresponding sets of output vibration response data in the frequency domain. Then, from relations between m corresponding complementary sets of n input transfer functions characterizing the correlation between each set o f input acoustic pressure-related data and the reference data from one hand, a nd m sets of output vibration response data on the other hand, the structural transfer functions characterizing each said set of input acoustic pressure- related data are obtained. Finally, the dynamic vibratory characteristics of the acoustically excited structure are derived from the resulting structural transfer functions through usual calculation techniques.
Patent CA-2349353-A1 (CA)
Title: Downhole vibrator
Inventor: STOESZ CARL W
IPC: E21B31/113
Filed: 2001-05-31
Abstract: A vibratory impact tool for loosening downhole stuck objects in oil or gas wells, utilizing an internal piston spring which is repeatedly compressed by hydraulic pressure, and repeatedly released by lifting a dart valve from a valve seat on a flow-through piston. When the dart valve is lifted from the valve seat by a tripping spring, flow resumes through the piston, quickly lowering hydraulic pressure above the piston, allowing the piston spring to sharply drive the piston against the housing.  The dart valve is then reseated on the valve seat, causing the piston to again be driven against the piston spring, rapidly repeating the process.

Title: Reducing the distortion of optical pulses caused by the polarization mode dispersion in optical communication systems
Inventor: FRINS ERNA
IPC: H04B10/135
Filed: 2000-01-17
Abstract: When an optical pulse having any polarization at all is transmitted through an optical communication system, which is optically anisotropic, at least in sections, the optical pulse generally becomes distorted due to the different velocities of the various polarization components. This distortion of the optical pulses reduces, in particular, the maximum transmission rate of the system.     A remedy is provided, on the one hand, by a method where, functioning in response to the detected transmission quality of the communication system, a polarization-controlling device for setting the polarization of the optical pulse is driven in such a way that the transmission quality is maximized and, on the other hand, by an optical communication system, which includes an optical transmission medium, a device for determining the transmission quality of the communication system, a regulating device, and a polarization-controlling device. The output signal from the device for determining the transmission quality of the communication system is applied to the regulating device, which drives the polarization-controlling device to change the polarization of the optical pulses in such a way that the transmission quality is optimized.

Abstract: Thermosetting and thermoplastic elastomers are provided having magnetic filler packed within the elastomeric matrix (31) and capable of being aligned and energized, before, during or after the molding of the elastomer. The magnetically-filled elastomers therefore provide useful permanent magnetic fields which are physically soft. The magnetic filler is aligned within the elastomeric matrix and energized by subjecting the magnetically-filled elastomer to magnetic energy before, during and/or after molding of the magnetically-filled elastomer. A particularly preferred magnetically-filled elastomer is the reaction product of a urethane-forming compound having at least two urethane-forming reactive sites, an elasticizing diol or triol, and a diisocyanate reacted in less than stoiciometric amounts to allow for the formation of urethane linkages involving less than about 85% of the urethane-forming reactive sites. Vibration dampening devices employing elastomers and, more particularly, the magnetically-filled elastomers of the present invention are also provided.

Title: Outer loop/weighted open loop power control in a time division duplex communication system
Inventor: SHIN SUNG-HYUK
IPC: H04B7/005
Filed: 2000-03-22
Abstract: Outer loop/weighted open loop power control controls transmission power levels in a spread spectrum time division duplex communication station. A first communication station (110) transmits a communication to a second communication station including target adjustment information generated at the first station on the basis of measured error rates of communications from the second station to the first station. The second station receives the communication and measures its received power level. Based on in part the received communication's power level and the communication's transmission power level, a path loss estimate is determined. A quality of the path loss estimate is also determined. The transmission power level for a communication from the second station to the first station is based on in part weighting the path loss estimate in response to the estimate's quality and based on the receive target adjusted by the target adjustment information transmitted from the first station.

Title: Automatic initialization of an advanced set-top box in a cable television system by downloading software or firmware over the cable system
Inventor: BIRNBAUM JACK M
IPC: H04N7/24
Filed: 2000-04-14
Abstract: A method and system for programming a set-top terminal in a cable television system includes automatically launching a boot code object from the read-only memory of the set-top terminal when the terminal is powered or reset. The boot code object will automatically identify and acquire and implement the base platform code, which may be acquired from the memory of the set-top terminal or downloaded from a data transport stream provided over the cable television system. Once the base platform code is executing, the boot code is terminated.  The base platform code then automatically locates and acquires the operating system object and any other resident applications of a native suite, which may be pulled from the memory of the set-top terminal or downloaded from the cable system. The base platform code authenticates the native suite and then launches the native suite to provide full set-top terminal functionality.
